Cyclo Alkanes

- Carbon compounds can form rings
- Follow the same naming rules and add cyclo- in front of the parent chain
- When numbering, you can count clockwise or counterclockwise, but where you start (#1) should be on one of the side chains because you are using the lowest numbering system

Examples of Cyclo Alkanes:

Aromatics

- When a cyclic 6 carbon chain forms, it can create a resonance structure called Benzene

Organic chem

Alkenes
- Compounds with double bonds end in -ene

- Put a # in front of the parent chain that indicates where the double bond is

- More thn one double bond changes the parent chain slightly

- Double bond always has priority (when choosing the direction of numbering)

- Any rime more than one double bond occurs, you add adi, atri, atetra...

- The longest chain has to include the double bond




Alkynes
- For compounds with triple bonds use -yne ending

- Follow all the same alkene rules

- The longest chain has to include the triple bond




ORGANIC CHEMISTRY
- There are more carbon compounds than all ionic compounds combined
- The study of carbon compounds is called organic chemistry
- Carbon can have multiple bonds and form many different shapes
- Hydrocarbons have three types of formulas:

1) Molecular formulas
C6H14

2) Condensed Structural Formula
CH3-CH2-CH2-CH2-CH2-CH3

3) Structural Formula



Nomenclature of Hydrocarbons
- One molecular formula can have a number of different structures
- Isomers are compounds that can be drawn in more than one way


Naming Alkanes
1) Name the longest chain by using the correct suffix and adding "ane"
2) Locate any branches by number carbon atoms (use the lowest possible number system)
3) Name branches by using appropriate suffix and -yl ending (Alkyl branches)
4) If there are more than one of the same alkyl group, number each one and add the multiplier number in front of the branch name
